Overview

Biology is often viewed today as a bipartisan field, with molecular level genetics guiding us into the future and natural history (including ecology, evolution, and conservation biology,) chaining us to a descriptive scientific past. In Darwinian Detectives, Norman Johnson bridges this divide, revealing how the tried and true tools of natural history make sense of the newest genomic discoveries. Molecular scientists exploring newly sequenced genomes have stumbled upon quite a few surprises, including that only one to ten percent of the genetic material of animals actually codes for genes. What does the remaining 90-99% of the genome do? Why do some organisms have a much lower genome size than their close relatives? What were the genetic changes that were associated with us becoming human? As molecular biologists uncover these and other new mysteries, evolutionary geneticists are searching for answers to such questions. Norman Johnson captures the excitement of the hunt for our own genetic history. Through lively anecdotes, he explores how researchers detect natural selection acting on genes and what this genetic information tells us about human origins.

Editorial Reviews

From the Publisher
"Just about every topic under the banner "why genetics is important to understand and still amazing to many professional biologists" is covered in this compact book. What a delight to read about some well-chosen examples, glittering in succinct detail and presented in a manner designed to intrigue and captivate a general audience."—Reports of the National Center for Science Education

"Along with addressing issues like ID and creation science, Johnson goes on to show how molecular biology confirms and extends the conclusions that scientists have used to support evolution. This is why this book is such a good read. Through his antidotal way of writing, Johnson is able to explain how researchers have discovered the ways natural selection work on gene, but he does it in a way that one just starting in their study of evolutionary biology can understand."—The American Biology Teacher

"This volume is a worthwhile update for anyone who wants to see where comparative genomics is taking us."—Quarterly Review of Biology
